Was bedeutet der Fehlercode?
The transmission control module (TCM) can request higher engine speed before a downshift, and the request is sent to the engine control module over the CAN network. It is purely an information code showing that the engine control module has refused the requested speed increase, for example when the vehicle speed is too low.
Mögliche Ursachen
- The transmission control module (TCM) has requested higher engine speed before a downshift, and the engine control module has not allowed it
Was Sie tun können
- 1Because the code is informational it normally does not need remedying. Still check the gear shifts on a test drive
- 2If gear shifting quality is poor, have a workshop read the transmission control module (TCM)
Symptome, die Sie bemerken können1
- Gear shifting may feel poorer
